Chapter XVIII: Book II: is a deduction of the more special laws of nature and duties

of life, so far as they follow from the course of life shown above to be recommended by God and nature as most lovely and most advantageous; all adventitious states or relations among men aside. The three first chapters are of a general nature.

In Chapter I., he reviews the circumstances that increase the moral good or evil of actions. Virtue being primarily an affair of the will or affections, there can be no imputation of virtue or vice in action, unless a man is free and able to act; the necessity and impossibility, as grounds of non-imputation, must, however, have been in no way brought about by the agent himself. In like manner, he considers what effects and consequents of his actions are imputable to the agent; remarking, by the way, that the want of a proper degree of good affections and of solicitude for the public good is morally evil. He then discusses the bearing of ignorance and error, vincible and invincible, and specially the case wherein an erroneous conscience extenuates. The difficulty of such cases, he says, are due to ambiguity, wherefore he distinguishes three meanings of Conscience that are found, (1) the moral faculty, (2) the judgment of the understanding about the springs and effects of actions, upon which the moral sense approves or condemns them, (3) our judgments concerning actions compared with the _law_ (moral maxims, divine laws, &c.).

In Chapter II., he lays down general rules of judging about the morality of actions from the affections exciting to them or opposing them; and first as to the degree of virtue or vice when the ability varies; in other words, morality as dependent on the _strength_ of the affections. Next, and at greater length, morality as dependent on the _kind_ of the affections.

Here he attempts to fix, in the first place, the degree of benevolence, as opposed to private interest, that is necessary to render men virtuous, or even innocent, in accordance with his principle that there is implanted in us a very high standard of necessary goodness, requiring us to do a public benefit, when clear, however burdensome or hurtful the act may be to ourselves; in the second place, the proportion that should be kept between the narrower and the more extensive generous affections, where he does not forget to allow that, in general, a great part of human virtue must necessarily lie within the narrow range. Then he gives a number of special rules for appreciating conduct, advising, _for the very sake of the good to others that will result therefrom_, that men should foster their benevolence by the thought of the advantage accruing to themselves here and hereafter from their virtuous actions; and closes with the consideration of the cases wherein actions can be imputed to other than the agents.

In Chapter III., he enters into the general notion of Rights and Laws, and their divisions. From _right_ use of such affection or actions as are approved by the moral faculty from their relation to the general good, or the good of particular persons consistently with the general good, he distinguishes the _right_ of a man to do, possess, demand, &c., which exists when his doing, possessing, &c. tend to the good of society, or to his own, consistent with the rights of others and the general good, and when obstructing him would have the contrary tendency. He proceeds to argue, on utilitarian principles, that the rights that seem to attend every natural desire are perfectly valid when not against the public interest, but never valid when they are against it.

Chapter IV. contains a discussion upon the state of Nature, maintaining that it is not a state of anarchy or war, but full of rights and obligations. He points out that independent states in their relation to one another are subject to no common authority, and so are in a state of nature. Rights belong (1) to individuals, (2) to societies, (3) to mankind at large. They are also natural, or adventitious, and again perfect or imperfect.

Chapter V. Natural rights are antecedent to society, such as the right to life, to liberty, to private judgment, to marriage, &c. They are of two kinds--perfect and imperfect.

Chapter VI. Adventitious rights are divided into Real and Personal (a distinction chiefly of legal value.) He also examines into the nature and foundation of private property.

Chapter VII. treats of the Acquisition of property, Hutcheson, as is usual with moralists, taking the _occupatio_ of the Roman Law as a basis of ownership. Property involves the right of (1) use, (2) exclusive use, (3) alienation.

Chapter VIII. Rights drawn from property are such as mortgages, servitudes, &c., being rights of what may be called partial or imperfect ownership.

Chapter IX. discusses the subject of contracts, with the general conditions required for a valid contract.

Chapter X. Of Veracity. Like most writers on morals, Hutcheson breaks in upon the strict rule of veracity by various necessary, but ill-defined, exceptions. Expressions of courtesy and etiquette are exempted, so also artifices in war, answers extorted by unjust violence, and some cases of peculiar necessity, as when a man tells a lie to save thousands of lives.

Chapter XI. Oaths and Vows.

Chapter XII. belongs rather to Political Economy. Its subject is the values of goods in commerce, and the nature of coin.
